With regards to your query, it does appear that Wirey Drgn is missing from the enemies list because it was mistakenly labeled as a boss in our internal data. You're the first person to mention that in ten years.
It's been restored to the enemies page now.We have been slowly working on improving the FF6 coverage, though that process has indeed been very, very slow. I can't actually guarantee anything any more because we actually have next to nobody who works on the site any more - it's not like six or eight years ago when we had ten to twenty people who were willing and had the patience and time to do the kind of work required to make the site have good data and be user-friendly (a lot of sites have one but not the other, as you've probably found).
I'm sure if we can get finished, the enemy skills will be better described, either in the walkthrough or in the more tabular data. When or if that will be, I wish I could tell you.
Hope to see you around more!
